Outline of Final Research Achievements

Brain-computer interface (BCI) has been attracted attentions as a communication tool for persons who cannot speak or move their hands to use a computer. To make BCIs more effective and useful, extracting of functional information from brain signals is key technology. In this study, we measured electroencephalography (EEG) signals and functional magnetic resonance imaging data during imagination of Japanese vowels, and performed vowel classification. As a result, the classification accuracy was higher when EEG cortical current signals were estimated from EEG and fMRI and used as the features than when EEG signals themselves were used.
